Abstract

We have used a neutron interferometer to observe the quantum-mechanical phase shift of neutrons caused by their interaction with Earth's gravitational field.Received 14 April 1975DOI:https://doi.org/10.1103/PhysRevLett.34.1472©1975 American Physical Society

• First, the lowest order multipole moment is determined by the source, not by gravity. For instance, the Earth has a non-zero monopole moment, which is just its total mass. Where gravity comes in is th [stackexchange, 3 points]
